trpms to improve mobility and depression in multiple sclerosis

Conditions: Multiple Sclerosis

Summary: this study is aimed to test the efficacy of 10 sessions of transcranial rotating permanent magnetic stimulation (trpms) paired with aerobic exercise or computerized cognitive training (ct) on mobility and depression symptoms in 40 individuals affected by multiple sclerosis (ms). participants in arm 1 will complete 10x40 minutes daily sessions of trpms+aerobic exercise. participants in arm 2 will complete trpms+computerized ct. primary outcomes for both arms will be assessed at baseline, at treatment end and after 4-week from the treatment end (follow-up).
